The combination with a furnace and a boiler having tubular flues, o fa bar mounted outside said furnace and over said boiler in fixed relation to the latter, a verticallymovable blast-tube yoked lto and laterally adjustable on said bar, said tube having a plurality of vertically-alined dischargeopenings therein and being adapted for lowering into the furnace behind the rear end of said .bolier to cause said openings to lie in registering parallelism with a vertical row of said fines, said tube being also adapted 'for having a partial rotary movement imarted thereto for directing said openings liivay from the boiler.

5. The combination with a furnace and a boiler having tubular flues, of a bar mounted over and in fixed relation to said boiler, a tul'ie-holder voked upon and adjustalily mounted on said bar, and a vertical blasttubc adjustably mounted in said holder and normally held Wholly withdrawn from said furnace.

6. The combination with a boiler having iues therein, and a furnace-wall adjoining the rear end of said boiler, of a bar mounted transversely over and in fixed relation to said boiler,`a tube-holder adjust-ably mounted on andin permanent bonded relation to said bar, and a blast-tube carried by said holder, said tube being adapted for lowering through the furnace-wall into proximity to the rear end of said boiler, said furnace-wall having a normally closed transverse opening therein through which said tube is lowered.

7. The combination with a boiler having fiues therein, and a furnace-Wall adjoining y the rear end'otl said boiler, of a bar ixedly mounted in transverse position upon the top of the boiler adjacent to the rear end thereof, a tube-holder adjustably mounted on said bar, said tube-holder and bar being permanently associated, and a blast-tube carried by said holder,saidtube being normally supported by said holder in a position Wholly removed from the furnace and being adapt-ed for lowering through' the furnacewall into operative proximity to the rear end of said boiler, said furnace-wall having a normally closed transverse opening `therein through which said tube is directed when in lowered position.

8. The combination with a boiler having' fines therein, and a. furnace-wall adjoining the rear end of said boiler, of a support mounted horizontally over the top of the boiler, a member adjustably mounted on said bar, and a vertically-movable blast-tube adjustab'ly mounted in said member, said tube being ermanently held in vertical position and a apted to be lowered into and elevated from said chamber.
